This is an impressive French made map of the world is drawn within a double hemisphere projection. The map displays a time when much of the world had been discovered and mapped yet many areas are drawn with a lack of detail and much speculation. Both Australia and the northwest portion of North America are nearly completely blank and mapped with speculative coastlines. Alaska is completely absent except for an archipelago representative of the Aleutian islands from reports of Russian explorers. Terre de Gama and Terre de la Companyappear northeast of Hokkaido. These lands were supposedly discovered in the 1600s but were deemed to not exist after voyages by Captain Bering and later Captain Cook reported their total absence. The Hawaiian Islands have yet to find their way on the map (they appear in this same map in the 1780s) but Easter Island is recognized in the southeastern Pacific. Both hemispheres are crowned with a Baroque style title cartouche popular amongst maps from this period. The map shows a conjectural projection of the Northwest Coast of America based upon a combination of the reports of James Cook and the earlier Russian Voyages in the mid-18th Century.The tracks of many of the17th and early 18th Century explorations in the Pacific are shown, including the routes of James Cook, along with Tasman's route in 1642, Quiros in 1605, Davis in 1686, Mendana in 1568, Anson's route in 1743, Magellan's route, and others.The projection of Australia is notable for its lack of a southern coastline. A report of the discovery of CapeCirconcision in January 1739 is shown, representing the most southerly land point discovered to date. No sign of the Antarctic Continent.
